Description
Only implementing types (of Interfaces) or Union members need
__isTypeOf
to help pick the right type name for the responses. This PR implements this behaviour by only generating__isTypeOf
for said object types.This PR also introduces
_parsedSchemaMeta
to hold metadata about the schema. This can help with performance and reduces complexity because we only parse through the schema once to collect meta about the types, and use the collected meta for subsequent generation.Note: This is an re-implementation for #10138, because this will be released as a breaking change instead of a new config.
